Coronavirus (COVID-19)

A new study is offering the strongest evidence to date of COVID-19 transmission from human to cat. The research builds on anecdotal reports but experts stress there is no evidence so far of viral transmission from domestic cats to their owners.

Several hundred million people around the world have safely received a wildly effective COVID-19 vaccine based on mRNA technology. So what exactly is an mRNA vaccine, where did the technology come from, and what other diseases could it be useful for?

Lockdowns, lab closures, funding cuts, and delays to ongoing clinical trials have all contributed to cancer research disruptions that may set the field back two years, according to new estimates made by the Institute of Cancer Research in London.

An experimental study has quantified the volume of aerosol particles generated by flushing toilets in a public restroom. The real-world research suggests even with lids closed flushing toilets can increase levels of ambient aerosol particles.

UK researchers are set to re-infect a cohort of recovered COVID-19 patients to study how the immune system responds to a second encounter with SARS-CoV-2. This trial expands on an ongoing study infecting healthy subjects to test vaccine efficacy.

A review article has presented 10 key scientific reasons why the virus that causes COVID-19 is predominantly spread though the air. The research adds to a growing chorus of experts saying the evidence for airborne transmission is “overwhelming”.

Stanford University scientists have conducted the first large survey into the modern phenomenon of "Zoom Fatigue." They found women suffer from greater exhaustion following videoconferencing compared to men, and the researchers think they know why.

A new review into the relationship between COVID-19 and hearing problems is suggesting a number of audio-vestibular symptoms can be associated with the disease. The review found hearing loss, tinnitus and vertigo can all be associated with COVID-19.

A team of scientists is investigating the bi-directional relationship between COVID-19 and diabetes. The researchers suggest SARS-CoV-2 infection may be triggering the onset of diabetes and a global registry has been set up to track this phenomenon.

Several effective COVID-19 vaccines have been developed in rapid time but was that the easy part of the process? Are intellectual property protections and for-profit pharmaceutical companies now getting in the way of vaccinating the world's population?

A new peer-reviewed study is suggesting mRNA COVID-19 vaccines can prevent infection and reduce risk of onward transmission. The research is one of several real-world studies looking at the first few months of vaccinations.

A new report from the CDC has found more than three-quarters of people presenting at a hospital with COVID-19 were either obese or overweight. The findings build on a convincing body of research linking disease severity with higher BMI.
